Create a PolarDB-X 1.0 data source

Security risk reminder

When you use OceanBase Data Transmission Service, you can add its public IP address CIDR blocks automatically or manually. This action might create security risks. Using this product, you acknowledge and accept the potential security risks. You must take basic security measures, such as using complex passwords, restricting open ports for each CIDR block, using authentication for internal API calls, and regularly reviewing and restricting unnecessary IP address CIDR blocks.

OceanBase Data Transmission Service adjusts automatically added whitelists or security groups by adding or deleting entries based on business requirements and security risks. Do not use the IP address segments in these whitelists or security groups for purposes unrelated to OceanBase Data Transmission Service. If you use these IP address segments for other purposes, any resulting issues are not covered by the OceanBase Data Transmission Service Service Level Agreement (SLA). For more information about the whitelists and security groups that are automatically or manually added by OceanBase Data Transmission Service, see the Add Whitelist documentation.
